Subject:      Sample large datasets with observations logically removed
Content-Type: text/plain; charset="us-ascii"

Greetings!

If we run the code below, we will get the error indicated in the log.
Now imagine the data set have is very large and we do not want to make any
change on it.
Then how can we avoid such errors when sampling the data set? Thank you.
